TIME SERIES DATA FOR 3D FLOOD MAPPING

Beata Wieczorek

Abstract

Thanks to the ability to collect information about large areas and with high frequency in time areas threatened by floods can be closely monitored. The effects of flooding are socio-economic losses. In order to reduce those losses, actions related to the determination of building zones are taken. Moreover, the conditions to be met by facilities approved for implementation in such areas are determined. Therefore, satellite data from the Earth observation program play a key role in assessing water conditions that are variable in space and in time. The article specifies the probability of flooding the area in the vicinity of the ?yna River valley in the S?popol commune. The analysis has been carried out for areas where floods have occurred. The spatial data from airborne laser scanning and satellite radar interferometry was examined in the context of its usefulness in the determination of the maximum possible extent of flooding. In order to transform data into useful information, it was necessary to integrate both the spatial and temporal dimension of the SAR time series. Finally, digital terrain model with high resolution was created.
